A former Broward sheriff’s detective has pleaded guilty to a federal civil rights violation for making a false arrest to help ex-attorney Scott Rothstein’s $1.2 billion Ponzi scheme.

Jeff Poole told a federal judge on Thursday that he illegally arrested a woman in June 2009 under orders from the right-hand man to then-Sheriff Al Lamberti. Poole identified the high-ranking officer as Lt. David Benjamin, who ran the internal affairs division.
